## Collaborating in Hypersonic Space

Standing ready as a new LLNL capability in the hypersonic mission space, the Energy Matter Interaction Tunnel (EMIT) facility houses a cold-flow, open-jet, blowdown wind tunnel to test materials in clean, high enthalpy, high-speed flight environments.





 



 

 



 





 

 

 

### "To study materials in their flight environment, we have to bring that environment to Livermore,” says Aric Rousso, Facility Lead of the Energy–Matter Interaction Tunnel (EMIT) project at the Laboratory.



 



 

 



 



 



   
 

 



 

 



 





 

 

 

## Our Goals

Designed for high-throughput and small-scale material response to hypersonic flow, EMIT supports a range of programmatic, fundamental research, and external sponsor needs that require high resolution data for physics-based modeling and simulation. EMIT additionally includes a robust diagnostics suite and considerable staff expertise in material science and high-speed flow measurement. We have the in-house experience and capabilities to drive both materials and diagnostic development from concept to testing at large-scale national facilities.
